EDWIN P. SEARS, OF BUFFALO, NEW YORK.

WAGON-SEAT FASTENER.

SPECIFICATION forming part of Letters Patent No. 282,786, dated August '7, 1883.

Application filed May 29, 1883. (No model.)

To all whom it may ooncewu,

Be it known that I, EDWIN P. SEARS, of the city of Buffalo, in the county of Erie and State of New York, have invented anew and useful Improvement in Seat-Fasteners, of which the following is a specification.

This invention relates to an improvement in that class of seat-fasteners which are composed of a tongue or hook secured to the seat or its standard and a socket secured to the box or body of the wagon, and adapted to receive and hold the tongue or hook of the seat.

The object of my invention is to provide the tongue with a simple and reliable locking device, whereby it is readily secured in the socket when desired; and my invention consists of the improvements in the construction of the seat-fastener, which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved seat-fastener, showing the tongue secured in the socket. Fig. 2 is a similar View, showing the lockingbolt raised; Fig. 3 is a horizontal section in line 00 :0, Fig. 1. Fig. 4 is a vertical section in line 3 3 Fig. 1. Fig. 5 is an end elevation at right angles to Fig. 1. Fig. 6 is a perspective view, showing the position. of the parts preparatory to inserting the tongue in the socket.

Like letters of reference refer to like parts in the several figures. I

A represents the side pieces of the body or box of the vehicle, and B the side piece or standard of the seat.

0 represents the hook or tongue secured to the seat, and D the socket secured to the in ner side of the box or body of the vehicle. The tongue 0 is provided at its lower end with a rearwardly-extending projection or shoulder,.0, adapted to engage under the socket, and the opening (I in the socket is made long enough to permit this enlarged lower end of the tongue to pass down through it, so that after inserting the tongue in the socket and pushing the seat backward until the projection c bears against the under side of the rear portion of the socket the tongue is held in the socket against vertical movement in a wellknown manner.

6 represents a vertical sliding bolt attached to the tongue 0, and f is a recess, groove, or opening formed in the socket D for the reception of the lower end of the bolt when the tongue has been placed in the socket, with its lip c engaging against the under side of the socket, as hereinbefore described. The tongue 0 is provided with a vertical slot, g, in which the bolt 6 moves vertically. This slot is preferably enlarged on the rear side of the tongue, as represented in Fig. 3, or made of dovetail form, and the bolt is constructed on its rear side with laterally-extending upright ribs or flanges h, running in the enlargementst of the slot 9, or the bolt is made of dovetail form to correspond with a dovetail slot.

When the parts are constructed as last above described, the bolt 6 can be introduced into the slot 9 from the rear side of the tongue before the latter is secured to the seat. After the tongue is secured to the seat the bolt is confined in the slot, in which it is, however, free to move vertically.

The tongue may. be constructed with a bridge-piece, j, which extends across the slot.

and forms a stop for the thumb-piece 7c of the bolt, and a support whereby the tongue rests on the socket. When the seat is to be secured to the body of the vehicle, the tongue is placed over the socket, as represented in Fig. 6, and then lowered into the socket. The lower end of the bolt 6 strikes on the upper side of the socket, and the bolt remains stationary while the tongue is further lowered. WVhen the bridge-piece j strikes on the upper side of the socket, the projection c 011 the tongue has passed below the lower side of the socket. is now moved backward until the tongue rests against the rear side of the socket, when the projection c bears against the under side of the rear portion of the socket. 111 this position of the tongue the bolt 6 coincides with the recess f and drops into the latter, thereby looking the tongue against horizontal movement, and securely holding the tongue in the socket. Upon raising the bolts onboth tongues, secured to opposite ends of the seat, the tongues are free to be moved forward in the sockets, and to be lifted out of the same. A number of sockets may be secured, at suitable distances apart, to each side of the body or box of the vehicle.

The seat All of these sockets are plain castings, and

vertically on said tongue or hook, and to enter the recess f1, substantially as set forth.

2. The combination, with the socket D,

having a recess, f, of a tongue or hook, C, provided with a vertical slot, 9, and a fasteningliooliilf, sliding in said slot, substantially as set EDWVIN P. SEARS.
